I have a 2015 G force 500ho and it seems to get between 16 and 20 MPG. is this what I should expect. I have been driving it in the hills on dirt roads and a little on streets.

I did a 50 mile trip and it said empty by the time I got back to the staging area. We checked it, and It looked like I had 1.5 to 2 gallons left. Lot of hard riding, Quick stops, fast take offs, climbing and river fording. So for 5 gallons on easy open trail, you should be able to get 90 to 100 miles if kind of steady and fast. But if your digging and putting it to it, I'd guess a bit over 50 per tank.

so 5 gallons and 100 miles is 20 mpg. thats what I get. thanks. Really thought it would be double that.

I think the last time I took my machine out, that the engine is finally broke in properly. I got a lot better fuel mileage, and it was mostly on dirt roads. Did around 25 miles and used a gallon. Some mudding and thicket crossings done, but not enough to really effect the overall result.
